T all wwut t may con/c0771.:

Be it known that'I, WILLIAM P. Kookc- GEY, of Brooklyn, in the county otl Kings and State of New York, have inventedcertain new and useful Improvements in Electriclghting Apparatus t'or \"\f'ay8tations, ot. which the followingI is a specification.

My invention relates to means 't'or lighting way-stations otl railways in advance ol", during, and, itv necessary, for a short time at'ter the passage ot' a traiirby the station, the purpose being to render unnecessary the attendance ot an agent at the station or stations during 4the later hours, when only an occasional passenger boa-rds or leaves the train at such stations. Under existing systems it is necessary either to have an agent present at the station to light the same whenever a train is due, or else to leave the station dark, to the annoyance and inconvenience ot passengers. The former plan involves considerable expense and unnecessary labor, and the latter plan is ol? course unsatisfactory to the traveling publie. To remedy these dit'ticulties l adopt the cmistruction represented in the accom panyiig drawings, in which Figures l. and 2 are diagrams illustrating the circuits and circuit-closing devices which I employ to secure the lighting ot the lamps at and during the time required and their extinction when the need for them is passed, Fig. l showing the lighting-circuit closed, and Fig. 2 showing the same broken or open.

A and B indicate the railsI ot the track, the rail l5 bein provided with two insulated sections, l. and 2, the remainder ot the track being uninsulated. From the insulated section il a wire or coinluctor, c, passes to and con nects with the helix ot an electrosmagnet, C, thence to a battery, l), and finally to the rail A or other ground-connection. Facing the electro-magnet (l is a pendulous or movable circuit-closer, E, carrying an armature, t), which, when the magnet is energized, attracted thereby, and completes a local circuit containing the lamps to be lighted and the battery or other source ot' electricity tor supplying the necessary current tothe lamps. This circuit is formed by the circuit-closer E and contact spring or plate c, line or conductor d,

lamp or lamps F, line e, and battery G, which latter is connected by a short line, f, with the circuit-closer E. From this it will be seen that 'whenever the circuit-closer E makes contact with the contact spring or plate c the circuit will be closed from battery G through the local circuit and the lamps F, rendering` the lamps luminous; and it will also be seen that they will continue .luminous so long as the battery or generator continues to furnish the necessary current and the circuit-closr-r E maintains contact with thel finger c.

'lhe 4circuit ot' which insulated sect-ion 'l forms a part is only closed Atfor a briei time, or while the train passing over it, and is located at such distance in advance ol' the station as to cause lights to be lighted in advance ot' the arrival of the train, the magnet C becoming inactive as soon as the train leaves the insulated section l. and destroys the circuit which it had previously completed through the bridging of the rails by its wheels and axles.

'zlhe circuit-closer E should be so arranged that it will stand in any position io which it is moved-a result which may be accom pl ished either by applying slight friction Athereto or by making the portion above the pivot slightly heavier than the portion below the same, so that it shall act as a counter-balance to hold the circuit-closer in one or the other of these two positions as soon as the coui'iter-weight passes the vert-ical plane ot" the pivot, though I prefer to arrange the circuit-closer to swing horizontally, in which case it will stand where placed.

For the purpose ot' extinguishing the lights when the train leaves the station or reaches a suitable distance beyond the same I enr ploy a second electro-magnet, H, one end of the helix of which connects by a wire or con- A ductor, g, with insulated section 2, and the other end of which is connected by similar wire or conductor, 7i., with the wire or conductor a at a point between electro-magnet C and battery D, so that-when the rails A B are bridged by the wheels and axles of the train on the insulated section 2 a circuit will be completed through said wheels and axles, the insulated section 2 of rail B, wire g, electro-magnet H, wire 71 battery D, line a., and rail A or ground-connection, thereby energizing magnet ll and causing' it to attract the armature l) of the circuit-closer E. This construction causes the circuit-closer to move away from electro-magnet C and out of con.- tact with the contact-plate c, thus breaking the light or lamp circuit and causing the lamps to go out or cease to bc luminous.

The device is extremely simple and ciiicient in practice.

Separate batteries may of course be used for the electro-magnets C and H, though for the sake of economy l prefer to employ but one for that purpose.

It will also be seen that the lamp-battery G may be utilized to energize the electro-magnets C and H, as well as furnishing the necessary current for the lamps; but this is not deemed desirable, because of the strength and volume of currentrequired, and because, also, of the greater danger of failure of the apparatus to operate.

Having thus described my inven tion, what l claim isl. In combination with a local electric circuit containing a light-giving device and located at the station or point to be lighted, a second circuit adapted to be closed by a train passing along' the track at a point in advance of the station or light, an electro-1nagnet included in said second circuit, and a circuitlcloser included in the light circuit, and adapted to be attracted by the electro-magnet and to complete-the light-circuit whenever the second circuit is completed through the bridging of the rails by the train.

2. The combination of rails A B, the latter provided with insulated section l, an electromagnet, C, and battery D, connected in circuit with insulated section l and with ground or rail A, a light-circuit containing the circuit-closer E and contact c, and an armature carried by the circuit-closer and placed within the field of magnet C, whereby the circuit closer is attracted and caused to complete the light-circuit when the rails are bridged at the section l.

3. ln combination with a railway-track having' insulated rail-section s, one in advance of the point to be lighted, a local light-circuit, a circuit-closer included in said circuit, electro-magnets arranged Vto move the circuitcloser in opposite directions, and two independent circuits, each including one of the insulated sections and one of the electro-inagnets, substantially as shown, whereby the entrance of a train upon the iirst insulated section is caused to effect the closing of the light-circuit and the entrance of the train upon the second insulated section is caused to break or destroy the light-circuit.

4L. In combination with lines A and B, the latter vhaving insulated sections l and 2, wire or conductor a, connected at one end with the insulated section l and at the other end with rail A or other ground-connection, electromagnet C, a battery, D, included in said conductor a, electro-magnet H, having one end of its helix connected by a line or conductor, g, with section 2, and its other end connected by a line or conductor, 71 with a battery, which is in turn connected with the railA or other ground, wires d e f, lamps F, and battery G, constituting a local light-circuit, a circuit-closer, l, and contact-spring c, for completing said light-circuit, the armature b of ,the circuit-closer being located between the /niagnets C and H, all substantially as shown and described.

5. In combination with an electric lamp and a local circuit therefor, a circuit-closer included in said circuit, an electro-magnet adapted to attract the circuit-closer and toconiplete the light-circuit, lines or conductors extending from the electro-magnet to an in-u sulated section of the rail in advance of the light, and a ground-connection, whereby the entrance of a train upon the insulated section is caused to energize the electro-magnet andconiplete the light-circuit- 6. In combination with an electric light and an electric circuit therefor, including a battery or other generator, a circuit-closer included in the light-circuit, electro-magnets arranged to act upon the circuit-closer and move it in reverse directions, and two independent circuits, each including a battery or electric generator and an independent insulated section of the track, one of said sections being located in advance of the lamp, whereby the entrance of a train upon the first insulated section is caused to complete the circuit through one of said electro-magnets, which thereupon attracts the circuit-closer and completes the light-circuit, and the entrance of the train upon the second of the insulated sections is caused to complete the second circuit and'move the circuit-closer to destroy the lightcircuit, substantially as set forth.

In witness whereof l hereunto set my hand in the presence of two Witnesses.
